SLIDING-DOOR LOCK.

SPECIFICATION forming part of Letters Patent No. 509,130, dated November21, 1893.

Application filed December 5 1892. Serial No. 454,111. (No model.) Y

To all whom it may concern:

Be it known that we, JOHN H. LEWIS and ALBERT WEENINK, both citizens ofthe United States, residing at Chicago, in the county'of Cook and Stateof Illinois, have invented certain new and useful Improvements in Car-Door Fasteners, of which the following is a full, clear, and exactdescription, that will enable others to make and use the same, referencebeing had to the accompanying drawings, forming a part of thisspecitication.

This invention relates to an improved fastening-device or catch forsliding-doors, and is more especiallyintended for use on freightcardoors, as will be hereinafter set forth.

Figure 1 is a broken-away front elevation; Fig. 2,a vertical section online 2, Fig. 1; Fig. 3, a plan of the catch part; Fig. 4, the inner orreverse side ofthe catch; Fig. 5, a section on line 5, Fig. 1; and Fig.6, a broken-away detail.

Referring to the drawings, A may represent a sliding-door to which thecatch B is attached, and C a doorpost to which the locking-bolt D isattached. Y

The back end of the catch is preferably of the circular form shown andis pivotally attached to the door by bolt E inserted therethrough andsecured on the inside by nut a. Between this end of the catch and thesurface of the door is a disk-plate F (Figs. 3, 4 and 5), provided onopposite sides with holding-pins o. ct which are to be inserted in thedoor to prevent the plate from turning. This plate is provided with asocket-shoulder a? (Fig. 5), having a square aperture a3 (Fig. 4), whichts into the bolt-aperture in the catch.

The bolt E is provided with'square sides a4 corresponding to the squareaperture in the plate F and socket-shoulder thereof and also with thespherical head d5, so that the same cannot be removed from the outside.The edge of the plate F is cut away at one side, as at b (Fig. 4),providing stop-shoulders b b2. This leaves the edge of the catch projectover the cut-away edge of the plate F; the projecting edge beingprovided with the rigid stoplugba. This arrangement provides for theturning of the catch from a horizontal to a vertical position and backagain to a horizontal or locking position, as the stop-lug b3 will comealternately in contact with shoulders h Y b2 and confine the movement ofthe catch within that limit. The object of this is to throw the catch upout of the way when the door is opened, as the catch will projectloeyond the edge and be in the Way, especially on car-doors. When thearrangement is such that the catch would not be in the Way, it can besecured rigidly to the door in a horizontal position, and the adjustablefeatures just described be dispensed with in the construction. Thebar-end of the catch is beveled as at d and provided with thelocking-shoulder d.

The bolt-plate G is secured to the door-post or frame C, and thelocking-bolt D movably attached thereto in a vertical position. Thisbolt-plate is provided With guide-straps d2 d3 which loosely retain thebolt in its relative position and permits of an endwise movement. Thebolt d4 passes through the strap d2 and rigidly fastens the plate G inplace. The locking-bolt is provided near its longitudinal center withthe elongated slot g through which the bolt d4 passes, and which limitsthe up and down or endwise movement of the locking-bolt. The strap cl2is provided with the square aperture g (Fig. 6), and the bolt d4 with acorresponding square shoulder g2 (Fig.

2), fitting the aperture g so that the bolt d4 cannot be turned from theoutside.

The locking-bolt is normally in its down or locking position and has thelower end beveled, as at g3, so that when the beveled surface d of thecatch-bar comes in contact therewith in closing the door, thelocking-bolt is forced upwardly until the line of the shoulder d haspassed beyond, when the lockingbolt automatically gravitates into thelocked position shown in Fig. l.k

The catch is provided with the projection g4 (Fig. 3),having an openinghtherethrough. The lower end of the lockingbolt (Figs. 1 and 2), is alsoprovided with a projection or nosepart h also having an opening h2 whichpro- Vides for the attachment ot' a locking-seal ha indicated in dottedlines. The upper end of bolt D is also provided with an' opening h4 atwhich pointanother seal can be attached as indicated.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

IOO

1. In a door fastener, the combination of a securing plate adapted forattachment to the door, said plate being provided with a centralcylindrical hub having an angular bore, and being cut away at its edgeon one side to provide stop shoulders, a catch plate loosely pivotedupon the hub and having a catch at its outer end and a stop lugprojecting between the shoulders on the securing plate, and a boltpassing through the said two plates, said bolt having an angular` neckportion to fit the bore of the hub and prevent the securing plate fromturning, and a head to'overlap the end of the hub and hold the securingplate to the door and the catch plate to the securing plate;substantially as described.

2. In a door fastener of the character described, the combination of avertically arranged bolt-plate having guide straps, a locking boltsliding in said straps, said bolt having a centrallongitudinal slotthrough which the bolt for fastening the plate to the door frame passesto guide and limit'the movement of the sliding lock-bolt; substantiallyas described.

3. In a door fastener ofthe character described, the combination of adisk-plate adapted to be secured to the door, a bevel-ended catchpivoted upon a central hub of the plate, a vertically anchoredbolt-plate adapted to be secured to the frame of the door, and abevelended locking bolt sliding in guide straps on said plate, the catchand the locking bolt being provided with projections g4, 71,',respectively, adapted for the attachment of a seal lock; substantiallyas described.
